Refactor Claro's tableselect stylesheet

1. I have removed

[dir="rtl"] td.checkbox,
[dir="rtl"] th.checkbox {
  /* This is required to win over specificity of [dir="rtl"] td */
  text-align: center;
}

As above code doing the same

td.checkbox,
th.checkbox {
  text-align: center;
}

2. Improved nesting. Please review

Thanks @Gauravvv!

Made few additional cleanups in the MR to combine rules more efficiently, and removed one instance where nesting was used where it seemed to make the rule appear unnecessarily complex because of the nesting.

Committed 5b49fe3 and pushed to 10.1.x. Thanks!
